Patent ES-400659-A1 (ES)
Title: Method for separating hydrocarbons especially aromatic hydrocarbons and installations therefor
IPC: C07C7/04
Filed: 1972-02-25
Abstract: The method and installation are for the enrichment of one of the constituents of an initial mixture containing at least two hydrocarbons, especially with neighboring boiling points, and of which one at least possesses mobile hydrogens. Fractional distillation of this mixture is effected in contact with a phase containing an organo-metallic compound derived from a compound having itself mobile hydrogens and in which the metallic atoms are substituted in reversible manner for these mobile hydrogens. The vapor phase enriched in the hydrocarbon of the initial mixture which has the least affinity for metallic atoms is collected and an unvaporised phase enriched in the hydrocarbon of the initial mixture which has the most affinity for metallic atoms in partially metalled form is also produced. The affinity of the hydrocarbons concerned for the metallic atoms varies sometimes considerably from one hydrocarbon to the other and from one isomer to the other. By conducting operations continuously and in countercurrent in a distillation column relatively few stages suffice to obtain efficient separation of the hydrocarbons. The transmetallation reactions are facilitated by basic catalysts such as tertiary amines and chelating polyamines.

Title: Retracting bed mechanism
IPC: A47C17/38
Filed: 1972-10-11
Abstract: Mechanism for shifting a bed between horizontal and upright positions includes a pair of spaced apart vertical lift means coupled to opposite sides of an adjacent end of the bed and means for fastening the mattress to the headboard.

Patent ES-439476-A1 (ES)
Title: Method and apparatus for die cutting at least one blank in a sheet
IPC: B31B50/20
Filed: 1975-07-16
Abstract: A method and apparatus for die cutting at least one blank in a sheet and stripping waste material therefrom, characterized by forming a band of interconnected individual sheets by positioning the leading edge of the sheet in alignment with the trailing edge of the last sheet in the band, interconnecting the edges and then intermittently conveying the band of interconnected sheets through a platen press with a dwell for die cutting, followed by a dwell in a stripper station for removing waste and then separating the die cut sheet prior to transfer to a delivery station for subsequent handling. In the preferred embodiments, the separating of the sheets can be accomplished subsequent to the stripping of the waste material or during the stripping operation. To intermittently transport the sheet to the various stations, a drive roll is connected by a oneway clutch to an oscillating sector gear which is preferably disposed at the input side of the die cutting station and at the output side a tensioning device is utilized to maintain the sheet in tension during the dwell period in which a die cutting operation is performed.

Patent ES-454791-A1 (ES)
Title: Closed torus tire
IPC: B29D30/00
Filed: 1977-01-04
Abstract: A closed torus tire in which the cord or wire reinforcement ply, or plies, surround the inflation chamber which can retain pressure without being mounted on a wheel. The reinforcement ply is continuous circumferentially of the tire and axially in the crown and sidewalls. The circumferential ply edges are lap-spliced in the inner wheel-engaging part, rather than being folded around bead cores. The tire is made without use of a building core of any kind, thus avoiding the cost and difficulty of removing such core from the completed tire. The tire is made by wrapping the reinforcement ply, or plies, about a cylindrical drum to form a sleeve. An inner liner is then wrapped about the sleeve, a reversal of normal tire building practice. One circumfferential edge of the sleeve is then moved outward and axially over the remaining sleeve, beyond the other, unmoved edge. The one edge is then moved inward and axially under the other edge to form the lapped splice.
Patent ES-458987-A1 (ES)
Title: Paste distribution pipeline layout for multicolour printing machine - has level gauge controlled buffer reservoirs feeding printing points
IPC: B01F13/10
Filed: 1977-05-20
Abstract: An installation for preparing and distributing colour, esp. to screen printing machines with cylinders or frames, includes a number of pipelines circulating the basic printing mixtures and additive matter feeding each station via branch lines. Each of the pipelines has a metering pump which, when energised feeds the particular colour to the cylinder of frame under the control of a level detector in the screen cylinder, in the frame or in the roller trought. Arrangement eliminates the labour intensive aspect of the operation, so that many sources of error are also ruled out. There is no need for the frequent cleanings of the colour containers nor for the dumpings of unused pastes. Volatile ingredients cannot evaporate and the operation is generally speeded up.
Patent ES-459117-A1 (ES)
Title: Improvement of speed adjusting device used for loom such as device for fixing width between warps
IPC: D03C1/14
Filed: 1977-05-25
Abstract: Mechanism for treadle selection between a loom and a dobby or another loom, uses an auxiliary motor with a clutch to engage or disengage the motor shaft with the loom and dobby. Two toothed flanges are keyed to the shaft of the dobby or the shaft of the loom. At least one selector grips in the holes of the flanges to ensure the keyed fit of the flanges. A rotary unit is operated by the auxiliary motor to control the sliding action of the selector. At least one of the two planetary rim gears carried by the rotary unit is a wheel set with a different toth count on the rim wheels. These act with a different tooth counts of the teeth of both flanges. The effect is that after holding fast of the flange keyed to the shaft of the loom, and after the selector has been pulled back and the auxiliary motor has rotated the rotary unit on the planetary rim gears, the planetary rim gears give the low speed rotation of the flange keyed on the shaft of the dobby, until the selector ranges again into the holes of the flanges. Smooth and simple selection of the operating mode is achieved without acceleration of the moving parts when the auxiliary motor is in operation.

Patent ES-480810-A1 (ES)
Title: Device for the conversion of materials present in waste water and waste water sludges.
IPC: C02F3/18
Filed: 1979-05-22
Abstract: This device transforms the substances, particularly noxious substances such as faeces, contained in sludge and waste waters, into innocuous substances. It comprises one or several bodies circulating into a digestion or activation tank, arranged so as to emerge completely from the waters or sludge on one side and to be immersed completely on the other side. The part of these bodies which is disposed on top in the emerged position is at the bottom in the immersed position and vice versa. These bodies have the disadvantage that, in the long run, the sludge settles inside the bodies. An anaerobic fermentation may take place within said settled sludge, wherein the noxious substances become rotten. In order to avoid the deposit of sludge into the hollow bodies, laterally closed hollow bodies are used but which are opened on the top and on the bottom and which are subdivided by means of a wall parallel to the upper and lower openings.
